It's a view that I once held and it's easy to agree with reflexively because it appears correct at a surface level.
Poor white people hearing about "white privilege" does alienate them, it implies they've failed even with a kind of starting advantage and can be taken as an invalidation of the hardships they face. Rather than inviting them to be empathetic to the additional issues faced by others it instead prompts them to be defensive of their own difficulties.
When GP frames the issue as one of income inequality and not racial inequality, he's partially correct. On the surface it is an income inequality problem, but for the black community that income inequality is the result of wealth inequality that is itself a product of historic racism.
The same goes for the wage gap which he's dismissive of. The usual argument here is that women simply choose lower paid work. But if we look past that surface level analysis there are still issues with employers not wanting to hire women because they think they might get pregnant, underpaying them because they're less likely to complain, or whether the types of work performed by women should be lower paid in the first place.
